允議招親 The Widow Relents
那婦人道：「既然幹得家事，你再去與你師父商量商量看，不尷尬，便招你罷。」八戒道：「不用商量，他又不是我的生身父母，幹與不幹，都在於我。」婦人道：「也罷，也罷，等我與小女說。」看他閃進去，撲的掩上後門。那妇人道：「既然干得家事，你再去与你师父商量商量看，不尴尬，便招你罢。」八戒道：「不用商量，他又不是我的生身父母，干与不干，都在于我。」妇人道：「也罢，也罢，等我与小女说。」看他闪进去，扑的掩上后门。
逐句解 Line by line
The woman said, “Since you can manage the housework, go and talk it over once more with your master; if there's no awkwardness in it, I'll take you in.”
那婦人 nà. 幹得家事 “able to do the household work,” 得 the resultative de. 不尷尬 “no awkwardness, nothing amiss.” 招你 “take you in (as husband).”
Bajie said, “No need to talk it over — he is not my own natural parent; whether I do it or not rests with me alone.”
生身父母 “the parents who bore one.” 幹與不幹，都在於我 “to do or not to do lies entirely with me,” 都 dōu. Bajie repudiates even his master's authority to advance the match.
The woman said, “Well then, well then — let me speak with my girls.”
也罷，也罷 “very well, very well.” 等我與小女說 “let me tell my daughters.” The widow's assent moves the scheme toward its next stage.
He watched her slip inside and, with a bang, pull the back gate shut.
閃進去 “to dart in.” 撲的掩上 “to swing (it) shut with a bang,” 掩上 “to close over,” 上 the complement. The closing gate ends the wooing and returns Bajie, elated, to the others.
The widow's response seals Bajie's self-betrayal. Persuaded that this ungainly monk can at least “manage the housework,” she agrees in principle — go settle it with your master, and if nothing stands in the way, she will take him in. The match she was refused in the hall she now half-grants at the gate, to the one disciple who sought it out.
Bajie's reply throws off the last restraint. He needs no leave from Tripitaka, he declares, for the Master is “not my own natural parent,” and the decision rests with him alone. Having earlier hidden behind the emperor's command and his brothers' refusal, he now repudiates even his teacher's authority — the plainest measure yet of how completely the temptation has taken him.
The banged-shut gate closes the covert scene as the slammed inner door closed the public one, but to opposite effect: where the earlier door shut the pilgrims out in rebuff, this one shuts on a bargain half-struck. Bajie will return to the others puffed with success, unaware that Wukong has witnessed all — and that the four saints' contrivance is now poised to spring its trap.
